The power grid, as we know it, has not changed since its invention: if not obsolete, it is not sufficiently advanced in many networks to meet the reliability and efficiency standards being pursued today, and may not even be adequate to meet current and future energy demands. In the conception of electrical systems, so far, energy is considered to flow in one direction only, being generated at power plants and transported to consumers for use.
However, in order to comply with the principles governing the evolution of the energy sector towards a more efficient state, which drive decarbonization and aim to increase the contribution of renewable technologies, it is necessary to address a series of changes that allow the evolution of the electricity system avoiding existing inefficiencies, some of which can be addressed and compensated by implementing a "Smart Grid" such as: losses in transmission and distribution, lack of visibility and responsiveness when monitoring in real time the state of the grid and responding proactively to events such as overloads, short circuits or equipment failures, inefficient demand management or limited integration of renewable energies.
A Smart Grid is an electric power distribution system that integrates advanced technology, such as sensors, smart meters, automated controls and bidirectional communications, to improve the efficiency, reliability, security and sustainability of the electricity supply.
Features
These smart grids integrate different IT tools and state-of-the-art technology to provide an effective response to the volatile demand for electricity and fluctuations in its production. Likewise, this technology enables fluid communication between the installation and the user, in both directions, as well as the control and monitoring of energy consumption. This means that, in the face of demand peaks or variations in renewable energy generation, the grid can automatically adjust to maintain a constant balance.
In addition to all this, Smart Grids are characterized by:
- Real-time monitoring: Smart Grids employ advanced sensors and metering technologies to monitor energy consumption and production in real time. This provides accurate demand data and enables instantaneous proactive adjustments to ensure consistent and efficient supply. It improves the reliability of power supply by enabling faster detection and response to faults and events on the grid.
- Integration of renewable energies: By enabling a more efficient integration of renewable energy sources, such as solar and wind, dependence on fossil fuels is reduced and greenhouse gas emissions are reduced.
- Two-way communication: Smart Grids foster two-way communication between users and the grid. Consumers can make informed decisions about their consumption, taking advantage of flexible tariffs based on demand. In addition, the grid can send signals to reduce or increase demand at specific times.
- Quality and reliability: The incorporation of intelligent technologies improves the resilience and reliability of the grid. In the event of failures or extreme weather events, the grid can automatically reconfigure itself to minimize the impact and restore service more quickly.
- Efficient demand-side management: Implements demand-side management technologies, such as load control systems and dynamic tariffs, which help balance energy supply and demand more efficiently.
- Consumer participation: Enables greater participation and control by consumers through smart meters and energy management applications.
- Energy efficiency: Uses advanced technologies to reduce losses and optimize energy flow, improving overall system efficiency.

Social benefits
- Ensure efficiency, safety, reliability and quality in the supply and operation of the energy system.
- They allow users to know their consumption and the tariff applied in real time, as well as to manage their energy consumption in order to discharge their surplus to the power grid or store it for use at a later time.
In short, Smart Grids represent a necessary evolution in electricity infrastructure to meet today's challenges. As we move towards a more conscious and responsible era, Smart Grids are emerging as an essential component in building a smarter and greener energy world, thanks to their ability to adapt to demand in real time, foster distributed generation, promote environmental sustainability and improve resilience.
